The solid-state emission of these security inks can be fine-tuned over a wide emission range (∼100 nm) with rapid response (milliseconds) to chemical stimuli.
Consequently, the obtained energy difference was less than 40 meV, thus demonstrating the feasibility of varying the QD growth parameters for bandgap engineering towards the THz emission range.
FE exhibited an absorption peak around 760 nm (mass extinction coefficient ~13.0 L g−1 cm−1 in toluene) and broad tunable emission range from 1000 to 1400 nm with a peak of ~1010 nm in the NIR-II window under the excitation of an 808 nm laser (Fig. 1b).
A Waldmann UV236B irradiation system equipped with two fluorescent CF-L 36 W/UV6 light tubes (emission range, 280 360 nm; peak, 324 nm; Waldmann Medizintechnik, Villingen-Schwenningen, Germany) was used for UVB irradiation, at a mean irradiance of 2.20 mW/cm2 at a distance of 15 cm and the irradiance of exposure was monitored by a calibrated Waldmann photometer.
In this paper, we propose a compact planar device in infrared (3 12μm) that has a high emission range from 5μm to 8μm while simultaneously serving as a broadband mirror for the rest wavelengths by engineering its thermal emission characteristics.
Unfolded neutron spectra in the multiplier zones are slightly underestimated by calculations in the secondary neutron emission range of Pb(n, xn) reactions indicating the need of improvement in the (n, 2n) cross-section of Lead isotopes.
Modified H2 and L3 PhC-microcavity geometries are designed in order to achieve quality factors Q in the range of 1000 2000 with a good matching of the cavity mode spectral position with the emission range of the organic layer.
In the rock acoustic emission range, the outside world exerts many kinds of pressure.
Furthermore, the spectral response is very high in that emission range.
A broad peak in the visible emission range and a maximum of approximately 560 to 580 nm were observed for the ZFO thin films.
Taking the cylinder rock as the object, the embedding group intelligence sensor node is shown in Fig. 4, the acoustic emission range of the rock after splitting.
